DRAW-BAR-SPRING POCKET.

SPECIFICATION forming part of Letters Patent No. 426,148, dated April22, 1890.

Application filed March 3, 1890.

To all whom, it may concern.-

Be it known that 1, CHARLES T. SCI-IOEN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inDraw- Bar-Spring Pockets, of which the following is a full, clear, andexact description.

The object of this invention is to simplify and eheapen the constructionof the pockets for the draw-bar springs of railway-car couplings. In themaster car-builders standard pocket there are some forty-eight bolts,straps, and castings, which render the device costly, complex, andunduly increase the dead-weight of the car, aside from the considerationof expense in time and labor in assembling. The use of pressed steel inmaking railway-car fittings, as illustrated in several patentedinventions of mine which have gone largely into use, the increasedservieeableness of such fittings, their great durability and lightness,coupled with. their faculty of interchangeability with the castnnetalfittings which they supersede, demonstrate the feasibility of the moreextended use of this form of metal, and have led up to the presentinvention. It is proper to say here, however, that, broadly speaking,pressed-steel angle beams or plates have been applied to thedraft-rigging in substitution of the ordinary oak draft timbers, andalso that pressed-stecl pockets have been devised but these rendernecessary a reorganization of the draft-rigging, and this I purposewholly to avoid.

The invention consists, then, in draw-bar guideplates for the pockets ofrailway drawbar springs constructed of pressed steel or other wroughtmetal, and so as to be interchangeable with the standards in common use,substantially in the manner hereinafter more particularly set forth andfinally claimed.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is abottom plan. view, Fig. 2, a vertical sectional elevation, its planebeing in the line at a of Fig. 1; and Fig. 3 is a verticalcross-sectional elevation of the ordinary master carbuilders standardarrangement of the draw bar timbers and springpocket, showing my SerialNo. 342,385. (No model.)

guide plates substituted for those of the master car-builders standard.Fig. i is a perspective view of the guide-plate detached.

The longitudinal timbers (t and cross-timhers I), the springs c, andfollower-plates (Z may be as usual.

In order to construct the guide-plates of pressed steel or the like soas exactly to replace or interchange with those used in the masterear-builders standard, and to adapt them to be applied without new boltsand new bolt-holes, I make each of the pairs of guideplates enteringinto the construction of a draw-barspring pocket of a single piece ofplate-steel or equivalent wrought metal, as shown in detail especiallyin Fig. 4-that is to say, I take a piece or blank of the selectedmaterial, and by means of dies or other suitable tools, I form thecavity e, the bottom of which is to rest upon the timbers a, and thiscavity terminates in shoulders f, against which the follower-plates (Zabut and form the drawbar stops, and then the ends g of the plate returnto the plane of the bottom of the cavity and terminate in flanges 71,which are to be let into kerfs or grooves in the timbers a. 'The ends 9'receive the usual bolts i for securing the plates to the timbers. A ribj is projected from the bottom of the cavity, and it also is let intothe timbers a. Flanges 7t extend the length of the longitudinal edges ofthe plate, and are made integral therewith. Thus the guide-plate iscomplete in one piece.

The configuration and size of the plate may be varied as may berequired, and so, also, may be its mere details of structure. Theflanges, ribs, and shoulders also serve to add strength and stiffness tothe plate.

I prefer to make countersinks Z in the ends 9 to receive the heads ofthe bolts '5.

A guide-plate constructed in accordance with the principle of myinvention is interchangeable as to size, bolt-holes, centers, &c., withpresent standards. Moreover it reduces the number of parts comprising adraw-barspring pocket from fortyeight in the present standard to twentyin mine. It is also very much stronger, more durable, less liable todisplacement, and quite as cheap, if not cheaper.

\Vhat I claim 1. As an improved article of manufacture,

a guide-plate for draw-bar-sprin g pockets constructed for interchangewith the castings and other parts forming the master car-buildersstandard and other common standards, and to be applied in the ordinarydraft-ri ggin g, and comprising, essentially, a shouldered cavity toreceive the ordinary spring followerplates, bolt-holes to receive theordinary bolts 7 along the longitudinal edges, substantially asdescribed.

4. A guide-plate for draW-bar-spring pockets, constructed of wroughtmetal, preferably steel plate, die-shaped, and having a shoulderedcavity to receive the spring followerplates, a transverse rib at thebottom of the cavity, and ends provided with bolt-holes and longitudinaledge flanges, substantially as described.

5. A guide-plate for draw-bar-spring pockets, constructed of wroughtmetal, preferably steel plate, die-shaped, and having a shoulderedcavity to receive the spring followerplates, a transverse rib at thebottom of the cavity, ends provided with bolt-holes, transverse endflanges, and longitudinal edge flanges, substantially as described.

In testimony whereof I have hereunto set my hand this 1st day of March,A. D. 1890.
